Yes, home security signs are able to deter intrusions in New Orleans
Many studies confirm that security signs are effective when looking at ways to deter an intrusion. The reasoning is that the prowler will notice the signage and quickly determine that your residence is way too risky. Ultimately, why worry about cameras and motion detectors when a burglar can hit a less protected home down the road?
With that being said, the same studies note that a visible display isn’t the strongest intrusion impediment. A well-placed sign mainly discourages novices, but veteran thieves may want to discover how much security is really shielding your home prior to looking the other way. Other equipment, like cameras, have greater success at thwarting prospective invaders.
